Creamy Mashed Sweet Potatoes Recipe

These silky, creamy mashed sweet potatoes are made from roasted sweet potatoes, a whole head of roasted garlic, a bit of butter, and a touch of full-fat Greek yogurt for richness and tang. They make an excellent side for weeknight dinners or as a comforting addition to any holiday table.

We love classic mashed potatoes and mashed cauliflower, but mashed sweet potatoes bring a sweet-savory balance that pairs well with many mains. Roasting the sweet potatoes before mashing intensifies their flavor and sweetness compared to boiling, giving this recipe deeper caramelized notes and a naturally rich texture.

What is in mashed sweet potatoes?

This recipe uses a short list of wholesome ingredients that yield a smooth, flavorful mash. You will need:

• Sweet potatoes
• Olive oil
• Salt and pepper
• Unsalted butter
• Full-fat Greek yogurt (or sour cream)
• One head of garlic (roasted)

Mashed Sweet Potato Variations

This mashed sweet potato recipe is flexible. Here are several ways to adapt the flavor, texture, and cooking method to suit your preferences.

Cooking Method

Roasting gives the best flavor, but you can also boil the sweet potatoes:

1. Wash and quarter the sweet potatoes (leave skins on or peel, as you prefer).
2. Place them in a pot, cover with water, and add 1–2 teaspoons kosher salt.
3. Bring to a boil, then simmer until fork-tender, about 20–30 minutes depending on size.
4. Drain and proceed with the recipe as written.

Mashing Method

Choose the mashing method based on the texture you want. Make sure the sweet potatoes are fork-tender before mashing to avoid stringy results.

• Potato masher: Produces a slightly lumpy mash with texture.
• Food processor: Creates a very smooth, velvety mash.
• Hand mixer or immersion blender: Mostly smooth with a few small lumps; this recipe used an immersion blender for a creamy finish.

Flavor Ideas

Customize the flavor to make the mash sweet, spicy, or savory:

• Sweet: Stir in 1 tablespoon maple syrup or a bit of brown sugar for added sweetness.
• Spicy: Add a pinch of red pepper flakes or 1/2 teaspoon cayenne for heat.
• Seasoned: Sprinkle 1–2 teaspoons of a favorite seasoning blend on top as a garnish. Everything bagel seasoning or ranch-style seasoning work well.

Ingredients

• 5 large sweet potatoes
• 1 1/2 tablespoons olive oil
• 1/4 teaspoon salt, divided
• 1/4 teaspoon ground pepper, divided
• 1 head garlic
• 1/3 cup full-fat Greek yogurt (or sour cream)
• 2 tablespoons unsalted butter, room temperature
• Optional garnish: fresh thyme
• Optional topping: extra unsalted butter

Instructions

1. Preheat the oven to 375ºF (190ºC). Lightly oil a large casserole dish or baking sheet and set aside.
2. Trim the ends of the sweet potatoes and slice each one in half lengthwise. Trim the tip off the head of garlic to expose the tops of the cloves.
3. Arrange the sweet potato halves and the garlic head cut-side up on the prepared pan. Drizzle with olive oil and season with 1/8 teaspoon salt and 1/8 teaspoon pepper.
4. Roast for 20 minutes, then flip the sweet potatoes and garlic so they are skin-side up. Roast for another 20 minutes, or until the sweet potatoes are easily pierced with a fork.
5. Remove from the oven and let cool for about 10 minutes.
6. If you prefer a skin-free mash, scoop the flesh from the sweet potatoes into a large bowl. (If you like some texture, include the skins.)
7. Squeeze the roasted garlic cloves from their skins and add them to the bowl with the sweet potato flesh. Add the Greek yogurt, butter, and the remaining salt and pepper.
8. Use a hand mixer or an immersion blender to blend everything until smooth and creamy. Taste and adjust seasoning as needed. Garnish with fresh thyme and an extra pat of butter if desired, then serve warm.

Tips & Notes

• Texture: For the creamiest mash, remove the skins and use a food processor or immersion blender. For a rustic texture, mash by hand and leave some skin in.
• Greek yogurt: Adds tang and creaminess while cutting back on some of the butter for a lighter result. Sour cream is a good substitute.
• Roasting garlic: Roasted garlic mellows and becomes spreadable, infusing the mash with gentle, sweet garlic flavor.

Storage

These mashed sweet potatoes are ideal for make-ahead cooking. Once cooled, transfer to an airtight container and refrigerate for up to 5 days. To reheat, warm individual portions in the microwave or place the mash in an oven-safe dish and heat until hot. If the potatoes seem thick after refrigerating, stir in a splash of milk or a spoonful of Greek yogurt to loosen them while reheating.

Serving Suggestions

Mashed sweet potatoes pair beautifully with roasted or braised mains and are a natural fit for holiday menus. Try them with pork chops, baked chicken thighs, stuffed chicken breasts, pork tenderloin, smoked turkey, roasted turkey tenderloin, green bean casserole, mushroom gravy, or savory stuffing.
